Load balancing method based on fog node cooperation in fog computing network

Abstract

The invention relates to a load balancing method based on fog node cooperation in a fog computing network, and belongs to the technical field of mobile communication. The method comprises the following steps: firstly, carrying out related modeling on a communication process and a calculation process of a fog node cooperation scene; designing a cooperative contribution degree for screening cooperative fog nodes and a cooperative fog node screening algorithm based on multi-attribute decision; designing a cooperation contribution ratio coefficient xm based on cooperation contribution degree, andconstructing a system total overhead optimization problem model introducing the cooperation contribution ratio coefficient; finally, designing a load balancing algorithm based on the cooperation contribution degree for solving the optimal distribution result of the task loads among the fog nodes. According to the invention, on the premise of ensuring the feasibility, fairness and stability of fognode cooperation, the service load is reasonably shunted, and the system performance and QoE of users are improved.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a load balancing method based on cooperation of fog nodes in a fog computing network. Background technique [0002] In recent years, the in-depth development and application of technologies such as the Internet of Things (IoT), the fifth generation (5G) mobile communications, and artificial intelligence (AI) have accelerated the arrival of the era of the Internet of Everything, triggering intelligent transformation of the whole society. Emerging applications and services such as virtual reality, augmented reality, and intelligent video acceleration make it difficult for cloud computing to apply to all current network working modes. Fog computing (Fog Computing) emerged as an extension and supplement to cloud computing. Fog computing distributes and deploys resources and services such as computing, storage, system control, and network anywhere between the cloud and ter...

Problems solved by technology

[0006] (2) From the perspective that fog nodes in the network can cooperate with each other, the existing research considers that the performance indicators for optimization are relatively single, mainly focusing on delay and energy consumption indicators, and fail to design appropriate cooperative forwarding standards. Factors such as the fairness of collaboration between nodes and the stability of fog node execution tasks are considered together
